Racemoselective synthesis of ansa-metallocene compounds, ansa-metallocene compounds, catalysts comprising them, process for producing an olefin polymer by use of the catalysts, and olefin homo- and copolymers

A metallocene compound with the 4- and 7-positions on the indenyl moiety possessing large aromatic substituents is prepared in accordance with a method which produces substantially 100 percent racemic isomer. Advantageously, polymerization catalysts including the metallocene of the invention provide...

Beschreibung
Zusammenfassung:	A metallocene compound with the 4- and 7-positions on the indenyl moiety possessing large aromatic substituents is prepared in accordance with a method which produces substantially 100 percent racemic isomer. Advantageously, polymerization catalysts including the metallocene of the invention provide superior olefin polymerization results.
